TENNESSEE.

POWER-VI HEEL.

Application filed December 22, 1910.

Specification of Letters Patent.

To all whom i1 may concern:

Be it known that we, HURBERT S. BARTON and GEORGE E. BAUMGARDNER,citizens of the United States, residing at Highland Park, in the countyof Hamilton, State of Tennessee, have invented certain new and usefulImprovements in Power-WVheels; and we do hereby declare the following tobe a full, clear, and eXact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to power wheels, and especially that typeutilized at the stern of a steamer for propelling the same.

The object of the invention resides in the provision of a power wheel ofthe type named in which the blades thereof are pivotally mounted so thatwhen said blades are moved from their propelling zone they will offerthe least resistance to the water and thereby result in an economicutilization of the power necessary to drive the wheel.

Another object of the invention resides in the provision of meanswhereby the movement of the pivoted blades is limited during theirtravel through the propelling zone so that they will present at thattime the proper resisting surface to the water.

lVith these and other objects in view, the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully de scribed and particularly pointed out inthe appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings, wherein like characters of reference denotecorresponding parts in the several views; and in which,

Figure 1 is a plan view of a power wheel constructed in accordance withthe inven tion; the same being shown mounted in the usual frame commonto stern wheel steamers; Fig. 2, a section on the line 2-2 of Fig. 1;Fig. 3, a section on the line 33 of Fig. 1; and Fig. 4, a detailperspective view of one of the paddles of the power wheel, together witha fragment of the wheel drum.

Referring to the drawings, 10 and 11 indicate the rearwardly extendingbeams common to stern wheel steamers and depending from these beams areparallel spaced vertical members 12 and 13; said beams and verticalmembers constituting what is known as the well of a stern wheel steamer.

Mounted upon the beams 10 and 11 respectively are journal bearings 14and 15, in which is journaled a spider drum B. This drum includes a hub16, from each end of which radiate spokes 17, the spokes at each end ofthe hub being correspondingly arranged. Inner and outer annular bands 18and 19 respectively serve to brace the spokes 17, the outer face of theband 19 being disposed inward of the outer end of said spokes. Pivotallyhung between corresponding oppositely disposed spokes are paddles 20which have journaled on each side at their outer ends rollers 21 for apurpose that Will presently appear.

Mounted on the inner face of the vertical member 12 concentric with theaxis of rotation of the drum B is a guide rail 22, while another guiderail 23 is also mounted on the inner face of the vertical member 12 inparallel spaced relation to the guide rail 22 and disposed between thelatter and the periphery of the drum B. The guide rail 23 has itsterminals bent away from the guide rail 22 so as to form an enlargedentrance mouth at each end of the guide rail 23 to the space betweensaid guide rail and the guide rail 22.

Mounted on the inner face of the side member 13 is an arcuate guide rail24 which is disposed similar to the guide rail 22. Another guide rail 25similar to the guide rail 23 is also mounted on the inner face of thevertical member 13 in parallel spaced relation to the guide rail 24, andhas its ends bent away from the guide rail 24 so as to form an enlargedentrance mouth to the space between said guide rail and the guide rail23.

By this construction it will be apparent that as the drum B is rotatedby the usual means, the blades 20 are free to swing on their pivotsuntil the rollers 21 enter the space between the guide rails 22 and 23and the guide rails 24 and 25 respectively. When the rollers are sodisposed, it will be apparent that the blades 20 will be held againstpivotal movement and maintained in position to offer the properresistance surface to the water during the travel of the rollers 21between the respective guide rails. As soon as these rollers pass out ofthe space between the guide rails 22 and 23 and the guide rails 24 and25, the blades 20 move to inactive position, which will result in theuse of less power to propel the wheel and increase the sp d at which theboat is driven.

W hat is claimed is In a power wheel, the combination of a supportingframe including a pair of parallel spaced side members, a drum journaledon the frame between said side members, a plurality of blades pivotedaround the periphery of the drum transversely of the latter and havingtheir pivot disposed in alinement with one of the side edges of theblade, a pair of spaced guide rails mounted on the inner face of each ofsaid side members, and

a roller carried on the ends of each blade in alinement with the freeside edge thereof adapted to pass between said guide rails during therotation of the drum whereby the pivotal movement of said blades duringa portion of their travel is limited.

In testimony whereof, We affix our signatures in presence of twoWitnesses.
